Taking the information duplication between indicators, the grey relational analysis method is used to filter the key indicators, then the grey clustering evaluation model of nonlinear whitening right function is built to evaluate the safety of civil aircraft and the algorithm steps of the evaluation model are given. Finally, the model is validated by collecting the parameters of nine different civil aircrafts at home and abroad.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title content-type=\"abstract-subheading\">Findings<\/jats:title>\n<jats:p>The results show that the safety level of different types of aircraft is different due to the different index parameters, and to some extent, explain the rationality and scientificity of the method proposed in this paper to solve the problem.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title content-type=\"abstract-subheading\">Practical implications<\/jats:title>\n<jats:p>This paper gives a complete set of security assessment methods, which can be used to evaluate the security of civil aircraft in the operational phase quantitatively, scientifically and reasonably. Furthermore, it can be extended to other complex system security or stability assessment issues.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title content-type=\"abstract-subheading\">Originality\/value<\/jats:title>\n<jats:p>It not only provides the supplement and perfection of the safety assessment method in the theoretical system to a certain extent, but also provides a theoretical guidance to solve the problem of civil aircraft system safety assessment of civil aircraft manufacturing enterprise all over the world. At the same time, the nonlinear grey clustering evaluation model constructed in this paper is an improvement of the traditional model, which is, to some extent, the improvement of the grey clustering evaluation theory.<\/jats:p>\n<\/jats:sec>","DOI":"10.1108\/gs-10-2017-0034","type":"journal-article","created":{"date-parts":[[2017,12,21]],"date-time":"2017-12-21T07:19:07Z","timestamp":1513840747000},"page":"110-120","source":"Crossref","is-referenced-by-count":13,"title":["Research on safety evaluation of civil aircraft based on the grey clustering model"],"prefix":"10.1108","volume":"8","author":[{"given":"Bentao","family":"Su","sequence":"first","affiliation":[]},{"given":"Naiming","family":"Xie","sequence":"additional","affiliation":[]}],"member":"140","reference":[{"issue":"4","key":"key2020093022084370300_ref001","doi-asserted-by":"crossref","first-page":"745","DOI":"10.1134\/S0005117914040134","article-title":"Assessment of implementability and safety of aircraft flight paths by an on-board mathematical model","volume":"75","year":"2014","journal-title":"Automation & Remote Control"},{"issue":"4","key":"key2020093022084370300_ref002","first-page":"1351","article-title":"Unmanned aircraft systems in the civil airworthiness regulatory system: a case study","volume":"48","year":"1971","journal-title":"Journal of Aircraft"},{"key":"key2020093022084370300_ref003","first-page":"4","article-title":"Research on grey comprehensive evaluation model","volume":"10","year":"2004","journal-title":"Statistics and Decision Making"},{"issue":"3","key":"key2020093022084370300_ref004","doi-asserted-by":"crossref","first-page":"278","DOI":"10.1108\/GS-01-2015-0001","article-title":"Grey clustering evaluation of urban low-carbon transport development based on triangular whitenization weight function","volume":"5","year":"2015","journal-title":"Grey Systems"},{"issue":"11","key":"key2020093022084370300_ref005","first-page":"2743","article-title":"A novel trust evaluation model based on grey clustering theory for routing networks","volume":"8","year":"2013","journal-title":"Journal of Computers"},{"first-page":"4.4","article-title":"Boeing\u2019s safety assessment processes for commercial airplane designs","year":"1997","key":"key2020093022084370300_ref006"},{"key":"key2020093022084370300_ref007","unstructured":"Jones, S.M., Reveley, M.S., Withrow, C.A., Evans, J.K., Barr, L. and Leone, K.
